VALVE-muren.

To all whom it may concern:

Be it known that we, HERMAN MOODY and JOHN H. BLACKMAN, citizens of theUnited States, residing at Peoria, in the county of Peoria and State ofIllinois, have invented certain new and useful Improvements inValve-Lifters; and we do hereby declare that the following is a full,clear, and exact description of the invention,- which will enable othersskilled in the art to which it appertains to make and use the saine.

This invention relates to that class of tools known as valve lifters andparticularly to an adjustable tool for use in reinoving and replacingvalves in gas explosion engines.

y i The primary object of the invention `is to provide a tool for thispurpose having adjustable jaws whereby the parts of valves of any sizemay be readily and positively engaged where-by the work of reinovingorre- Yplacing the valves may be lightened and *'whereby, also, the timeincident to such Awork may be greatly shortened.

Another object is to furnish a tool of the Vcharacter describedwhosejaws are so constructed as to hold the washer'of the valve stem ina very positive manner.

Besides the above objects the invention j relates to certain details ofconstruction and arrangement of Vparts as will be fully `brought outherein. j

In the drawing forming a part of this application,

Figure l is a plan of one of the forms of tool with parts broken awayto, show the .in-

terior structures.

Fig. 2 `is a side elevation ofthe same also with parts broken away. l

Fig. 3 is an elevation of a portion of an engine showing a valve and theapplication of the tool thereto which involves our invention. j

Fig. e is an end elevation of the` jaws of the tool shown in theposition of engaging the usual washer of a valve stem.

A indicates the handle of one of the forms of tool, being preferablymade of pressed metal composed of two sections as shown in Fig.,2 andsuitably secured relatively, a portion of the upper section in Fig.libeing removed to show the interior structures. Thel said handle at itsouter or jaw end is flared edgewise asshown at Bin said'Fig. 1 where-Specification of Letters Patent.

by the inner walls of that end taper or are gradually contractededgewise toward the grasping end.

C represent two jaws lying` within the handle, their working endsextending outside the same while within the handle their edges adjacentopposite walls are formed at an angle, gradually narrowing inward asindicated in dotted lincs at C leaving a projection D to engage andslide upon the wall surfaces. The jaws extend some distance rearwardwithin the handle, their extreme inner ends being foi-ined at rightangles as at E and engage in recesses F in a nut G adapted to run upon ascrew H which extends through the rear wall A of the handle and having athumb piece J for its adjustment, there being` suitable provision forpre venting longitudinal movement of the screw relative to the handle.For instance, a spring K is interposed between the said nut G and thehandle wall A', but other means `the equivalent ofsaid spring may bee1nployed for the purpose, and other provision may be made for theassociation of the jaws with said nut G. I

L is an expanding` spring interposed between jaws 'C C by means of whichthe jaws `are kept separated to their widest limits.

In Fig. L both surfaces of the exposed jaw portions at their adjacentedges, or those .i Fig. fl.

5 is a compression spring` surrounding the valve stem V and lyingbetween the said washer 3 and the engine head. This construction whichis one of the common methods employed is shown in order that the mannerof use of our tool may be readily understood. .ln assembling ordisassemj bling the engine parts, it is necessary to lift the washer 3which is usually preferably side oftheA cylinder head to which a Chain Aor other flexible member S is attached, which lin turn is attachedadjustably to the tool. `The chain is employed as the t'ulcrum, the Vjwasher. l VVprovided tor holding'the valve on its seat. `:This consistsusually ot an inverted L ance andloss ot time.

provided with a recess 6 ot one form or aanothertoreceive thepin 4 asclearly shown 1n Fig. il.

In order to be enabled to litt-the said washer to allow the pin 4' to beremoved, a tool must be placed beneath the washento compress saidspring, but unless the valveis z prevented from raising due 'tothefriction of the washer or the spring thereon the` pin cannot be movedsince it will tollowthe In consequence of this, means 1s shaped member7, one end engaging said valve, and the other end depending at thetoolacting as a lever, there being apin 9 or a hook, or similar deviceto engageany Vvone of the links ot' the chain whereby an adjustmentv ofthe chain and tool relatively VVcan be made so as to obtain the bestresults. 25

It is observed by study of Figl wherein all the parts are assemblediormwork, that by! depressing the handle oi the tool its jaw end whichengages the washer 3 'will be raised to lift said washer againstthe.spring V.-

As the diameters of the washers vary in ditterentmakes of engines it isimportant Vthatthe jaws be made adjustable, otherwise as has been foundin previous practice serious trouble is experienced. In using a barbifurcated at its end to lie astride the valve stem with noy adjustmentof the bifurcations,

` the washer, if other than a certain size, will slip laterally upon thefaces or' the engaging lbifurcations and often tip and pass edgewise Jbetween them, causing considerable annoyy Consequently, we have providedthe adjustable jaws and turthermore employ the recesses "Mtherein inwhich thewasher may y.rest as clearly'ishown in Fig. 4, the ljaws beingadjusted. softhat fthe washer can justnicely enter ,and lie f semblingor disasscmbling.V

therein; the vertical walls of the recesses preventing any movement ofthe washer laterlally of the jaws. An adjustment to any particular jobthus expedites thework of asj l In the form .of tool in Fig. l therotation oftheV screw H in the proper directionrresults in moving thenut Gr toward the rear `or handle-end of the tool therebycausing theprojections or shouldersV D of the jaws to travel along the graduallynarrowing wall of the handle, causing the jawsto gradually approach oneanother until the proper amount of spread results.' Obviously, a'reversemovement of the screw results in l the spreading of the jaws. .Bythis'vmeans washers of any diameter maybe readily "ac- "cominodated,

ln order to provide forl the adjustment of Ythefchain relatively tothetool for any given v.engine the handle A is provided with a series ofholes l0 .a arranged-.-longitudinally thereof.
